Abstract
Description
Technical Field
[0001] This utility model relates to the field of aquaculture waste treatment technology, specifically a separation device for shellfish aquaculture waste. Background Technology
[0002] Shellfish farming, as an important part of aquaculture, is widely carried out globally. With the continuous expansion of shellfish farming scale, the problem of waste generated during the process has become increasingly prominent. Shellfish farming waste mainly includes shellfish remains, uneaten feed, shellfish feces, and other impurities in the farming water. If this waste is not effectively treated, it will not only seriously pollute the farming environment, affecting the growth and health of shellfish, but may also lead to eutrophication of the water body and disrupt the surrounding ecological balance. Because the various types of waste have different utilization values after separation—for example, shellfish remains can be processed into calcium fertilizer and building filler, and uneaten feed and feces can be processed into organic fertilizer—separation is carried out simultaneously with the treatment of aquaculture waste.
[0003] Currently, methods for treating shellfish aquaculture waste are relatively limited and have many shortcomings. In some small-scale aquaculture, manual sorting is often used, where workers manually pick out larger waste such as shellfish shells from the aquaculture waste using simple tools. This method is not only labor-intensive and time-consuming, but also extremely inefficient and costly. Furthermore, manual sorting makes it difficult to achieve precise waste classification; smaller pieces of feed, feces, and impurities may remain, failing to achieve ideal separation results.
[0004] Some farms have tried using simple filtration devices, such as filters with different pore sizes, to filter farm waste. However, such methods can only initially separate larger particles of waste. For smaller particles of uneaten feed and feces, the filters are prone to clogging and require frequent cleaning, thus increasing maintenance workload.
[0005] In conclusion, developing a separation device that can efficiently separate shellfish farming waste is of great practical significance for promoting the sustainable development of the shellfish farming industry. Utility Model Content
[0006] The purpose of this invention is to provide a separation device for shellfish aquaculture waste to solve the problems mentioned in the background art.
[0007] In view of the above problems, the technical solution proposed by this utility model is as follows: A device for separating shellfish aquaculture waste includes a first separation box and a second separation box. The first separation box is higher than the second separation box and is connected to it. A vibrating plate is elastically connected inside the first separation box. A driving component is also provided inside the first separation box to drive the vibrating plate to move vertically. An ultrasonic vibrating plate is installed on the inner wall of the first separation box, and the ultrasonic vibrating plate is connected to the output end of an ultrasonic generator located outside the first separation box. A storage box is mounted on the top surface of the second separation box via a bracket. The storage box is used to store a surfactant solution. A first valve body is connected to the side of the storage box. A second valve body is connected to the side of the second separation box near its bottom. Both the first and second separation boxes have liquid outlet channels on their sides, and baffles slide within these channels. Both the top surfaces of the first and second separation boxes have sliding grooves, and the baffles slide within these grooves. Both the first and second separation chambers are equipped with electrically operated telescopic rods on their top surfaces. The telescopic ends of these rods are connected to baffles. Through the vibration of a vibrating plate and the ultrasonic action of an ultrasonic vibrating plate, the shellfish waste is initially separated. Larger and heavier shell fragments sink, while smaller uneaten food and feces enter the second separation chamber with the liquid. The second separation chamber utilizes the flotation effect of a surfactant solution to separate organic and inorganic matter. Because organic matter such as uneaten food has hydrophobic groups on its surface, the added surfactant binds to it, reducing its surface tension. This causes air to form stable bubbles around the organic matter and adhere to it, thus carrying the organic matter to the surface. Meanwhile, the mixed small shell fragments and other inorganic matter have hydrophilic surfaces, do not bind to the surfactant, and have a density greater than water, so they sink naturally. This process separates organic and inorganic matter. The electrically operated telescopic rods control the opening and closing of the baffles, allowing the waste that has been sitting in the first and second separation chambers for a period of time to enter the next stage.
[0008] Furthermore, the driving component includes a rotating shaft rotatably mounted inside the first separation box via a bearing, and the rotating shaft is located below the vibrating plate. An eccentric wheel is mounted on the outer side of the rotating shaft, and the eccentric wheel squeezes the vibrating plate. A motor is mounted on the outer side of the first separation box, and the output end of the motor is connected to the rotating shaft for transmission. When the eccentric wheel rotates, it periodically squeezes the vibrating plate, and with the help of a spring, it realizes high-frequency vertical vibration of the vibrating plate, thereby separating the heavier shell residue and the lighter impurities in the waste.
[0009] Furthermore, a connecting plate is installed inside the first separation box below the vibrating plate, and a spring connects the connecting plate and the vibrating plate. The spring resets the vibrating plate and maintains the continuity of vibration.
[0010] Furthermore, a protective box is provided on the outside of the first separation box, and the motor is installed inside the protective box via a base. Several heat dissipation slots are provided on the side of the protective box, and a protective cover is provided on the outside of the electric telescopic rod. The protective cover is installed on the top surface of the first and second separation boxes. The protective box and the protective cover protect the motor and the electric telescopic rod from water vapor and impurities, respectively, and extend the service life of the equipment. The heat dissipation slots ensure good heat dissipation when the motor is working and avoid overheating damage.
[0011] Furthermore, the top surface of the storage tank is connected to a feed hopper, which facilitates the replenishment of surfactant solution into the storage tank. The feed hopper has a large opening and an inclined design to reduce solution spillage and improve the convenience of feeding.
[0012] Furthermore, the bottom surface of the liquid outlet tank is set as a first inclined surface, and a guide strip is installed on the top surface of the second separation box. The top surface of the guide strip is set as a second inclined surface. The first inclined surface and the second inclined surface of the first separation box are connected, and the inclination of the first inclined surface and the second inclined surface are the same. Both ends of the guide strip are equipped with baffles to guide the liquid and light waste to flow smoothly from the first separation box into the second separation box and avoid residue. The baffles prevent waste from overflowing from the side and ensure a smooth separation process.
[0013] Furthermore, the bottom surfaces of both the second separation tank and the storage tank are designed as third inclined surfaces, which are inclined toward the first valve body and the second valve body, respectively. The first and second inclined surfaces are smoothly connected, and the third inclined surface guides the surfactant solution and precipitated impurities to flow toward the valve body, reducing residues, facilitating thorough discharge, and improving solution utilization and impurity cleaning efficiency.
[0014] Furthermore, a connecting frame is installed on the inner wall of the first separation box, and four pieces of coated fabric are connected between the connecting frame and the vibrating plate. The four pieces of coated fabric are connected to each other, and the coated fabric forms a flexible enclosure to prevent garbage and water from falling from the edge of the vibrating plate into the space below during vibration, while not affecting the up and down movement of the vibrating plate, thus improving the separation efficiency.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: the shellfish aquaculture waste separation device achieves the initial separation of shellfish waste through the vibration of the vibrating plate and the ultrasonic action of the ultrasonic vibrating plate. Larger and heavier shell fragments sink, while smaller uneaten feed and feces enter the second separation tank with the liquid. The second separation tank utilizes the flotation effect of the surfactant solution to separate organic and inorganic matter, ultimately solving the problems of low separation efficiency and poor effect of traditional separation methods.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figures 1-5This utility model provides a technical solution: a separation device for shellfish aquaculture waste, including a first separation box 1 and a second separation box 2. The first separation box 1 is higher than the second separation box 2 and is connected to the second separation box 2. A vibrating plate 16 is elastically connected inside the first separation box 1. A driving component is also provided inside the first separation box 1 to drive the vibrating plate 16 to move vertically. An ultrasonic vibrating plate 4 is installed on the inner wall of the first separation box 1. The ultrasonic vibrating plate 4 is connected to the output end of an ultrasonic generator located outside the first separation box 1. A storage box 10 is installed on the top surface of the second separation box 2 through a bracket. The storage box 10 is used to store surfactant solution. A first valve body 12 is connected to the side of the storage box 10. A second valve body 13 is connected to the side of the second separation box 2 near its bottom. Both the first separation box 1 and the second separation box 2 have liquid outlet grooves on their sides. The first separation box 1 and the second separation box 2 are equipped with baffles 7. The top surfaces of both the first separation box 1 and the second separation box 2 are provided with sliding grooves 5. The baffles 7 slide in the sliding grooves 5. The top surfaces of both the first separation box 1 and the second separation box 2 are equipped with electric telescopic rods. The telescopic ends of the electric telescopic rods are connected to the baffles 7. After the shellfish farming waste is put into the first separation box 1 along with the purified water, the driving component drives the vibrating plate 16 to vibrate. At the same time, the ultrasonic vibrating plate 4 generates ultrasonic vibration, which breaks up the waste agglomerates. The heavier shellfish shells remain on the vibrating plate 16, while the lighter impurities float to the top. After standing for a period of time, the baffles 7 are raised, so that the lighter impurities flow into the second separation box 2 with the liquid through the liquid outlet. The surfactant solution in the storage box 10 enters the second separation box 2 through the first valve body 12, which separates the inorganic and organic matter in the light waste. The organic matter floats to the top and flows out through the liquid outlet, while the inorganic matter is discharged through the second valve body 13. Finally, the debris in the first separation box 1 is cleaned up.
[0020] As an embodiment of this utility model, the driving component further includes a rotating shaft 17 rotatably mounted inside the first separation box 1 via a bearing, and the rotating shaft 17 is located below the vibrating plate 16. An eccentric wheel 18 is mounted on the outer side of the rotating shaft 17, and the eccentric wheel 18 presses against the vibrating plate 16. A motor is mounted on the outer side of the first separation box 1, and the output end of the motor is connected to the rotating shaft 17 for transmission. The motor drives the rotating shaft 17 and the eccentric wheel 18 to rotate. The eccentric structure of the eccentric wheel 18 causes the vibrating plate 16 to move up and down reciprocally. The spring provides a restoring force during the vibration process, forming a continuous and stable vibration, which promotes the separation of heavier shells and lighter impurities in the waste.
[0021] As an embodiment of this utility model, a connecting plate is further installed inside the first separation box 1 below the vibrating plate 16. A spring is connected between the connecting plate and the vibrating plate 16. When the eccentric wheel 18 pushes the vibrating plate 16 upward, the spring is stretched. After the eccentric wheel 18 rotates past the highest point, the spring contracts and drives the vibrating plate 16 downward, forming reciprocating vibration. The elastic potential energy and kinetic energy of the spring are converted into each other to maintain the continuity of vibration.
[0022] As an embodiment of this utility model, the outer side of the first separation box 1 is provided with a protective box 21. The motor is installed inside the protective box 21 through a base. Several heat dissipation grooves 3 are opened on the side of the protective box 21. The outer side of the electric telescopic rod is covered with a protective cover 6. The protective cover 6 is installed on the top surface of the first separation box 1 and the second separation box 2. The protective box 21 isolates the water vapor and salt in the breeding environment to prevent the motor from short-circuiting. The heat dissipation grooves 3 remove the heat of the motor through air convection. The protective cover 6 shields the electric telescopic rod to prevent liquid from splashing and affecting its telescopic performance.
[0023] As an embodiment of this utility model, the top surface of the storage tank 10 is connected to a feed hopper 11. The operator pours the surfactant solution into the storage tank 10 through the feed hopper 11. The funnel structure of the feed hopper 11 guides the solution to flow in in a concentrated manner, avoiding overflow and waste.
[0024] As an embodiment of this utility model, the bottom surface of the liquid outlet tank is further configured as a first inclined surface 14, and a guide strip 8 is installed on the top surface of the second separation box 2. The top surface of the guide strip 8 is configured as a second inclined surface. The first inclined surface 14 and the second inclined surface of the first separation box 1 are connected, and the inclination of the first inclined surface 14 and the second inclined surface are the same. Both ends of the guide strip 8 are equipped with baffles 9. The liquid and light waste in the first separation box 1 flow along the first inclined surface 14 under the action of gravity, and flow into the second separation box 2 through the second inclined surface of the guide strip 8. The baffles 9 restrict the flow range of the waste to ensure that it all enters the second separation box 2.
[0025] As an embodiment of the present invention, the bottom surfaces of the second separation tank 2 and the storage tank 10 are both provided as third inclined surfaces 20, and the third inclined surfaces 20 are inclined toward the first valve body 12 and the second valve body 13 respectively. The surfactant solution in the storage tank 10 flows toward the first valve body 12 along the third inclined surface 20; the precipitated impurities in the second separation tank 2 gather at the second valve body 13 along the third inclined surface 20, which facilitates centralized discharge.
[0026] As an embodiment of this utility model, a connecting frame 15 is further installed on the inner wall of the first separation box 1. Four pieces of plastic-coated cloth 19 are connected between the connecting frame 15 and the vibrating plate 16, and the four pieces of plastic-coated cloth 19 are connected to each other. The plastic-coated cloth 19 is flexible and expands and contracts with the up and down movement of the vibrating plate 16 to form a closed space, ensuring that the garbage is always separated on the vibrating plate 16 and preventing impurities from leaking to the bottom of the first separation box 1 and causing pollution.
